It was self defense. That’s what game and fish officials determined after a hunter shot a mountain lion north of Cokeville earlier this month. Adam Lancaster of Afton told the Wyoming game warden that he and his father were dressing out a buck mule deer they had killed when the lion moved in. Game and Fish officials say the lion was a sub-adult female apparently attracted by the smell of fresh meat – but they quickly add that such aggressive behavior toward humans is extremely rare. Lancaster told the warden the incident was over in seconds. The hunters left the lion carcass at the kill site and immediately contacted Game and Fish, which aided in quickly settling the incident as self-defense.

That's too bad. It sounds like a lot of good tasting meat was wasted.

Wow, I bet there's not a lot of house cats in your neighborhood!
